Abstract
The utility model provides an antitheft system for mobile phone. A charger, a charging switch, a detection circuit, a spiral telescopic lead and a mobile phone are sequentially and electrically connected; wherein, the detection circuit is connected with a displaying alarming device; the detection circuit detects whether the charging current of the phone is or not normal or a resistance at a charging interface is or not normal to judge the phone is or not offline and stolen, being accurate and reliable; moreover, the charging switch automatically switches and realizes the automatic charging for the phone. Without any change, the mobile phone is merely connected with the spiral telescopic lead, thereby complying with the common using habit of the user, and not influencing the phone appearance.
Description
Affiliated technical field
The utility model relates to a kind of mobile phone antitheft system, especially can allow mobile phone not do any variation, and it is antitheft only to connect realization by the cell-phone charging lead.
Background technology
Existing mobile phone seldom carries anti-theft feature, is undertaken antitheftly by wired or wireless independent alarm, all alarm will be combined with mobile phone and could realize that this has just influenced the appearance of mobile phone, and not really desirable, charging operations also bothers.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides a kind of mobile phone that allows not do any variation, and it is antitheft only to connect realization by the cell-phone charging lead, realizes the automatic charging operations of mobile phone simultaneously.
The utility model adopts following technical proposals: charger, charge switch, testing circuit, the flexible lead of helical form and mobile phone are electrically connected in proper order; Testing circuit is connected with displaying alarm.Adopt technique scheme, it is as follows to the utlity model has advantage:
1, mobile phone links to each other with the flexible lead of helical form, is convenient to mobile phone and uses, and is convenient to fixedly mobile phone location.
2, charge switch auto-closing can realize that mobile phone automatically charges.
3, testing circuit by the detection of handset charging current whether normal or charge port resistance whether normally judge mobile phone whether off-line be stolen, accurately and reliably.
4, mobile phone only is connected with the flexible lead of helical form, meets common people's use habit, does not also influence the mobile phone appearance.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure, 1, mobile phone, 2, the flexible lead of helical form, 3, testing circuit, 4, charge switch, 5, charger, 6, displaying alarm.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
In the drawings, charger 5, charge switch 4, testing circuit 3, the flexible lead 2 of helical form and mobile phone 1 order link to each other, and testing circuit 3 links to each other with displaying alarm 6.
Charging finishes charge switch 4 with automatic disconnection, and this moment, whether testing circuit 3 inspection cell-phone charging mouth resistance were normal, and resistance is excessive may to open circuit, the short circuit of the too small possibility of resistance, and the excessive and too small mobile phone 1 that all illustrates of resistance may be stolen.
No matter charge switch 4 disconnects and is closed, testing circuit 3, as long as detect undesiredly, all will report to the police by displaying alarm 6 reaches antitheft purpose.
Claims (1)
1. a mobile phone antitheft system is characterized in that, it is electrically connected in proper order by charger, charge switch, testing circuit, the flexible lead of helical form and mobile phone; Testing circuit is connected with displaying alarm; Testing circuit by the detection of handset charging current whether normal or cell-phone charging mouth resistance whether normally judge mobile phone whether off-line be stolen.
